In the routine work of laboratory diagnosis on the cases in 

 the clinic of the College of Veterinary Science of the University 

 of the Philippines, a peculiar type of myiasis-producing fly was 

 discovered. From clinic case 109 (carabao) a number of mag- 

 gots were obtained which were strikingly different, both in 

 appearance and in habit, from the other types of fly larvse 

 which had been previously observed. Adults raised from these 

 maggots were forwarded to Dr. J. M. Aldrich, of the Smith- 

 sonian Institution, through Dr. L. O. Howard, chief of the 

 Bureau of Entomology of the United States Department of 

 Agriculture. Doctor Aldrich reported the fly to be a previously 

 undescribed species, and one for which a new genus must be 

 erected. It has since been described by him as Booponus in- 

 tonsus. 1 Subsequent to the recognition of this distinct type of 

 myiasis, several interesting cases have been treated in the clinic 

 of the College of Veterinary Science, wjiich have furnished ex- 

 cellent oportunities for a detailed study of this peculiar fly.
